Description

Technical Field

[0001] The invention relates to the technical field of PD power supplies, in particular to an ultra-thin PD power supply. Background Art

[0002] PD power supply refers to a power supply with the PD fast charging protocol. The PD protocol is one of the current fast charging protocols and is a fast charging specification developed by the USB-IF organization.

[0003] An ultra-thin fast-charging mobile power supply with a PD protocol is proposed in the prior art. However, in actual use, while pursuing an ultra-thin design, the ultra-thin fast-charging mobile power supply on the market ignores the problem of heat generation during operation of the lithium battery board. The space in the ultra-thin installation shell is extremely limited. If the heat generated by the lithium battery board during operation cannot be dissipated in time, the lithium battery board will expand and deform or even explode, which is very likely to cause danger. Therefore, a PD mobile power supply that can dissipate heat for the lithium battery board in an ultra-thin shell is needed.
